Photosensitive composition and 1,3-dihydro-1-oxo-2H-indene derivative

Abstract

A photosensitive composition for short wave exposure use, which comprises (i) a sensitizing dye as a 1,3-dihydro-1-oxo-2H-indene derivative having a specified structure, (ii) an activator compound that generates chemical changes by its interaction with an electronic excitation condition induced by light absorption of the sensitizing dye represented by formula (I) and thereby produces at least any one of radicals, acids and bases and (iii) a compound whose physical or chemical characteristics are changed and maintained by undergoing reaction with at least one of radicals, acids and bases.

What is claimed is:  
     
       1. A photosensitive composition which comprises (i) a sensitizing dye represented by formula (I), (ii) an activator compound that generates chemical changes by its interaction with an electronic excitation condition induced by light absorption of the sensitizing dye represented by the formula (I) and thereby produces at least one of radicals, acids and bases and (iii) a compound whose physical or chemical characteristics are changed and maintained by undergoing reaction with at least one of radicals, acids and bases;                    
       wherein A represents S atom or NR 7 , Y represents a non-metallic atomic group which forms a nitrogen and/or sulfur-containing heterocyclic ring which does not contain a carbonyl carbon as a ring-constituting atom together with the adjacent A and carbon atom, each of R 1 , R 2 , R 3 , R 4 , R 5  and R 6  independently represents a monovalent, non-metallic group, and R 7  represents an alkyl group or an aryl group. 
     
     
       2. The photosensitive composition according to claim  1 , wherein the compound whose physical or chemical characteristics are changed and maintained by undergoing reaction with at least one of radicals, acids and bases is an addition-polymerizable compound having an ethylenic unsaturated double bond. 
     
     
       3. The photosensitive composition according to claim  1 , wherein the nitrogen and/or sulfur-containing heterocyclic ring which does not contain a carbonyl carbon as the ring-constituting atom represented by Y is selected from the group consisting of thiazoles, oxazoles, selenazoles, thiazolines, quinolines, imidazoles, indolenines, pyridines and dithiols. 
     
     
       4. A 1,3-dihydro-1-oxo-2H-indene derivative represented by formula (II);                    
       wherein A represents S atom or NR 7 , each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 8  and R 9  independently represents a monovalent non-metallic atomic group, and R 7  represents an alkyl group or an aryl group, wherein R 8  and R 9  are separate groups or combine with each other to form a five- to eight-membered ring. 
     
     
       5. A photopolymerization initiation system which comprises a sensitizing dye represented by formula (II) of claim  4  and an activator compound that generates chemical changes by its interaction with an electronic excitation condition induced by light absorption of the sensitizing dye represented by the formula (II) and thereby produces at least one of radicals, acids and bases. 
     
     
       6. A photopolymerization composition which comprises a sensitizing dye represented by formula (II) of claim  4 , an activator compound that generates chemical changes by its interaction with an electronic excitation condition induced by light absorption of the sensitizing dye represented by the formula (II) and thereby produces at least one of radicals, acids and bases, and a compound whose physical or chemical characteristics are changed and maintained by undergoing reaction with at least one of radicals, acids and bases.
